As in the said co-pending application 7 38,- 637 the present device ismounted upon la deck or platform 20 supported in any approved manner asby the uprights 21 from the Hoor or base 22.

Also erected upon this deck 20 is an upright 23 providing for bearingsfor the vertical shaft 24 and the elevator 25. These parts are similarin general effect and makeup to the disclosure of said (3o-pendingapplition and no especial description Will be introduced into thepresent case. Also, as in that case, a Weighing and dumping deviceindicated as an entirety at 26 is employed in conjunction with thebagging machine but performs no function other than delivering thecommodity in proper charges to the bagging machine.

The bagging machine comprises a turn table 27 which is rigidly connectedor integral with a gear 28 Which in turn is driven by the mutilated gear29. This mutilated gear 29 is c-arried upon the shaft 24 driven in anyapproved manner as from the motor 30 through the medium of the gears 31and 32.

It will be noted that as shown in the drawings the mutilated gear`29 is4provided with teeth about a third of its periphery,

' teeth upon the gear. 28, so that the gear 28 is rotated a fourth lof arevolution at each revolution of the shaft 24 and gear 29.

cated conventional] The turn table 27 is provided with a plurality ofcups 33similar to the corresponding cupsin said 'co-pending applicationand similarly provided about their perlpheries with upstanding,penetrating points' 34. These'several cups 33 are dishedv and pro-.vided with central'openings 35 which' communicate through tubularspokes 36 with the conduit 37 in the hollow shaft 38 which is within thehub of the turn table 27 such hollow shaft communicating through theconduit 39 with an exhaust mechanism indiat 40. So that,al1 of the cups33 are un er the action of exhaust except during such time as one ofsaid cups is opposite the unorificed part of the hollow shaft, asindicated by the hollow spoke 36 in Figure 13, at Vwhich time theexhaustds interrupted and at which time it is the intent that thekick-off mechanism to be hereinafter more fully described shall operate.

The construction of the turn table and the cups are also similar to theconstruction in said co-pending application. Located above the turntable is a guide block- 41 and mounted to reciprocate vertically inopenings in said block are dies 42 a'nd 43. Immediately below the guideblock 41 are die blocks 44 and 45 having openings registering with theopenings in the guide block 41 and so positioned that the dies 42 and 43in moving downwardly, guided by the guide block 41, will pass inshearing relation through the openings of said die blocks 44 and 45.

To actuate the dies 42 and 43 a crosshead v 46 is mounted upon a rod 47mounted to slide in the guide block 41 as also a guide for the crosshead46. Extending down wardly from the crosshead 46 is a rod 48 connected inany approved manner as pivotally to a cutting die 42 and a hollow rod 49extending downwardly and `connecting with the cutting die 43.

Extending also across from the hollow rod 49 and the rod 48 is a bar 50to the ends of which are attached links 51 and 52. By reciprocatingthese links 51 and 52, the die structure, consisting of and carrylngsaid dies 42 and 43, is made to reciprocate verti" cally. This structurefor operating the dies in proper timed relation with the other mechanismmay be any mechanical means found desirable for the purpose, here shownas comprising the cam wheel 53 mounted upon the shaft 24 and rotatingtherewith and with the gear 29. The camwheel 53 operates a lever 54,properly pivoted to move the link 55 which in turn operates a bell cranklever 56. This bell crank lever 56 is attached to a shaft 57 whichextends- 44 and 45.

transversely across the' 'machine and operates asimilar bell crank lever5.8l upon the opposite' side. These bell crank levers 56 and 58 connectwith links 59. and 60 which are pivoted as indicated at 61 in' Figure 1to the links `51 and 52.-- The movement of the bell crank leversl56 and58. is such that vthe links 59 and 60 are raised on an arc the bar 50and its` associated die structure.

The die blocks 44 and 45 also serve as supports for the fabric feedingmechanism which feedsv strips of fabric 62 from the rollers 63l and64`to proper position for engagement by the cutting-dies 42 and 43.

This fabric feeding structure comprises a plurality of sprocket chains65, 66, 67 and 68 which travel in properly positioned and milled grooves69 in the die blocks 44 and 45. These milled, parts provide openings 70for sprockets 71, 72, 3 and 74 which drive sald chains 65, 68respectively and are in turnA driven by a sprocket chain 75 makingproper contact v with all of said sprockets 71 and 74 inclusiveV andpassing over a s rocket 76 upon the shaft 77. A chain tig tener 78,.asshown at Figure 2, is also employed for taking' up the slack in saidsprocket chain 75. This shaft 77, which drives the sprocket chain 75,.is in turn driven from the gear 28 and for the purpose of proper timingand driving in proper relation, it is lpreferably accomplished through apair of idlers 79 and 80 as shown at Figure 15. It is to be understood,however, that any usual mechanical means for accomplishing the purposeis within the scope of the invention.

. These several sprocket chains also pass over idler sprockets 81, 82,83 and 84 set in the milled out parts 85 of the die blocks The chainscarry penetrating feeding members 86 which preferably are em loyed aspart of vthe links of the chains an are provided with upstandingpenetrating points 87. The fabric 62 passing from the rollers 63 and 64passes first over idler rollers 88 and 89 and then along supportingdecks 90 and 91, whereupon it is engaged by the netrating points 87 'ofth-"e feeding mem ers 86 and moved along between the adjacent pairs ofsprocket chains over the die openings in lsaid block. A rod or roller 92is provided as a tensioning means, being mounted upon a bifurcatedmember 93 actuated from the link 60 at the pivot 94 (see Figure 1) whichin` turn is connected with a lever 95 so that a vertical reciprocatingmovementis provided, This reciprocation of the roller or rod 92 servesto unwind from the rollers 63 and 64 at the proper time sufficient slackin fabric 62 to enable the feedwithout undue hindrance. It will be notey rotation of the that this feeding mechanism is driven from the gear 28which is drivenl with a step by step movement from the mutilated gear'29' i fabric by the descent of the die 43 is practically. simultaneouswith the discharge of the A commodity through said hollow shaft 49 uponthe fabric disk 62', as indicated at 97 in Figure 12. This cutting ofthe fabric disk by the descent of the dies also impales it upon thepenetrating points 34 and subjects it and the commodity thereon to theaction of the exhaust whereby the fabric disk and the commodity are heldto position vfor further operation; As the turn table rotates a fourthof a revolution, it is brought.

under the die 43 and a second fabric disk 62" is cut and impaled uponthe penetrating points 34 over and vupon the commodity thereon.

A sewing machine, indicated conventionally at 98, (see Figure 2) isemployed to stitch about the edge of the superposed fabric disks withpreferably `an overstitch indicated at 99 in said Figure 2 and Figure12. This completes the bag with the commodity contained therein whichsaid bag is in accordance with co-pending application Sr. No. 734,350,filed August 2G, 1924. The sewing of this bag is accomplished at thethird step inthe rotation of the turn table v 27. At the fourth'step thecompleted bag is removed from the machine by the kick-off mechanismshown in detail at Figure 14 and in-elevation and in perspective atFigure 1.

This kickoff mechanism comprises a bifur# cated lever 100 fulcrumed at101, the fingers of said lever being properly proportioned to span oneof the cups 33 by forcing downwardly the overhanging edges of the bagand assuming a position under the bag, then lifting to engage the edgesof the bag to lift it off of the cup, it having been heretoforeexplained that the action, 4Aof the exhaust upon the cup, bag andcommodity hassbeen relieved.

To oscillate this kick-off, a gear 102 is at tached to the pivot shaft101 and a. rack 103 is held in engagement with said gear by means of anidler 104. The rack 103 extends downwardly and is pivotally connect- 'edwith a bell' crank lever 105 which is in turn connected withthe link 59so that. as the link 59 is oscillated and reciprocated by The first thebell crank lever`.56, it in turn actuates the bell crank lever 105 andrack 103 to oscillate the kick-off 100 in proper timed relation to themovement of the turn' table, it being understood,l of course, that the-kickoff normally stands at vertical'or approximately so .while the/turntable vis rotating andoscillates through a complete cycle of operationonly while the turn table is at rest. Proper mounting and su portingdeyices for the kick-ofiE are indicated) by the upright 106 and brace107, it being understood of course y thatV any other convenient andapproved type of mounting would be the full equivalent of this specificmeans of mounting said oscillating kickoff'.

To properly function', it has been found that a specific type cuttingdie is of great advantage.` The type of die found best adapted for thepurposecomprises a sleeve which is preferably substantially aclosed-cylinder with, however, an intervalY indicated at 108 to providefor the proper expansionof the die intotengagment with the guide blockand die'blocks. Within the cutting sleeves 42 and-43, rings 109 and 110are em loyed. The die43 which cuts the first disk o fabric carries thering 110 which has a'central,

opening of sufficient size to permit thek tubu-V lar shaft 49 to extenddownwardly there! through andis provided with an annular furrow 111 toaccommodate the upstanding penetrating points 34 ofthe cups. As this dieand ring descend in ,cutting position, the

disk of fabric severed thereby is forcedl downwardly upon thepenetrating points and the* 'downwardly` extending-endl of the hollow sliaft49 extends downwardly into the dished partiofr thev cup'which isnowsubjectedtd exhaust at the time the commodity is introduced so that thelower. end of said hollowshaft is in engagement' with the fabric and thecommodity is not allowed to rebound from the discharge upon said fabric.As the die and hollow shaft are raised, the commodity 'and fabricareheld in proper position by the exhaust which is.

operating upon said. commodity and fabric. The ring 110 also serves as ameans for stiffening the cutting die 43, and as a means for connectingit to the hollow shaft 49 the pintles 112 being employed insertedthrough,

openings 113. l Y c The 'ring 109 in lthe die 42 is dished in its under`side so that asy it forces the fabric vdisk downwardly .upon thatalready placed upon "the penetrating points, the bulge produced by the.commodity' is accommodated in the dished outfportion 114 in said ring,an -opening 115 ybeing provided so that the eX- haust is notlinterrupted.' This ring 109 is likewise provided with the lannulargroove.

111 for the accommodation of the penetrating points. The forcing of thesecond disk downwardly upon the first' disk does not,

rio

' therefore, interrupt' th'e-faction lofthe exalst upon the commodityand Asuperpo'sed lThe opening 108- inthedieis intended to be at the sideof the, structure farthest re movedfrom the supporting rollers 63 and 64and at'what will be then-the extreme end u of the .fabric/fed so thatthere is at that point nothing 'makes provision 'for' the properresiliency of for the dies .to cut. This the die to always fit the guideanddie blocks without producing an interval where threads are not cutand therefore interrupt thel proper functioningr of the die.

'lhez'cutting edge of the die is i each case sections A116 whichcoincide 'withrlter vperimeter ofthe cylindrical die, Intermediate.these f coinciding sections the edge is scolloped as indicated at 117the bevel of the '117 being indicated. by the full and dotted two partsyforming the two edges 116 and lines at Figure 11. iThis formation of.the cuttingedge' has been found from vexperience tooperatsatisfactorily" and is believed tobean improvementfincutting dies.

To properly?, enable the sprocket chains and the feedingmembers 86 tofunction, the

d ile blocks are spaced away fromv t e an guide bloelfr;y bymeansofspacers 118, openings 119 beingprovided with the blocks 44, and forproperly securing these spacers in position'an orsecuring the die blocksto theguide block, said openings accommodating the screws or bolts inthe .us'a1` well knownma-nner.

In operation, .while the turn table 27 is I at rest, the fabric stripsaretfed forward by I cups, then positionedaimmediately beneath`thepsprocket chains'and feeding mechanisms 8 6until the ends ,of saidfabric strips are over the openings inthe die blocks 44 and 45 and'immediately underotheraised dies 42 and 43. In this position the diesdescend cutting simultaneously 'tw'o disks from the "extreme end of saidfabric strips, which said disks areforced downwardly upon thepenetrating points ofthe underlying vacuum said die openings.Simultaneously the weighingand dumping mechanism, .which does not enterinto-the'present invention, is

properly actuated to dump a charge of commodity through thehollowshaft49 upon the fabric` disksevered and positioned by the die 43, which saidfabric-'and the deposited comprocess is repeated by the dife43 and itsassociated parts and a'fabric disk is severed 4by the die 42 andilnpaled upon the penetratingv points 34 over'. and upon the depositedcommodity. The Vcommodity is then inclosed between two disks, both ofwhich are impaled upon the penetrating points and their perimeterssuperposed. The next quarter. rotation of the turn' tableV 27, the sameprocess is repeated bythe two dies and their associated parts and thepreviously filled cup is subjected to the actlon of the sewing machine98 which sewsabout the overhanging lsuperposed ed es of the diskcommodity in the thus completely. sewed and over-stitching, complete yinclosing the about bag.- The next quarter rotation of the turn table^27all of the hereinbefore described functions are repeated and thecompleted bag is moved to the fourth position. where it is acted-upon bythe kick-off which at this point descends by pressing down theover-hangingy seWed-edges of the bag until the fingers are under 4suchedges and then quicklyraising to throw off the bag. This completes oneentire cycle of operation of the machine 'and further actions of themachine are merely repeats and continuations of the cycle justdescribed..
